We have reviewed the unaudited standalone financial results of Clean Science and Technoiogy Limited (the "Company") for the quarter ended September go, zoz6 and the year to date results for the period April or, zoz6 lo September go, 2026, and the Unaudited Standalone Statement of Assets and Liabilities as on that date and the Unaudited Standalone Statement of Cash Flows for the half- year ended on that date which are included in the accompanying 'Statement of Unaudited Standalone Financial Results for the quarter and half year ended September go, zoz6' (the "Statement"). The Statement has been prepared by the Company pursuant to Regulation 33 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, zot5, as amended (the "Listing Regulations, zot S"), which has been initialled by us for identification purposes. 2. This Statement, which is the responsibility of the Company's Management and approved by the Board of Directors, has been prepared in accordance with the recognition and measurement principles laid down in Indian Accounting Standard 34 "Interim Financial Reporting" ("Ind AS 34"), prescribed under Section r33 of the Companies Act, zot3, and other accounting principles generally accepted in India. Our responsibility is to express a conclusion on the Statement based on our review. 3. We conducted our review of the Statement in accordance with the Standard on Review Engagements (SRE) z+ro "Review of Interim Financial Information Performed by the Independent Auditor of the Entity", issued by the Institute of Chartered Accountants of India. This Standard requires that we plan and per{orm the review to obtain moderate assurance as to whether the Statement is free of material misstatement. A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of ail significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. 4. Based on our review conducted as above, nothing has come to our attention that causes us to believe that the Statement has not been prepared in all material respects in accordance with the recognition and measurement principles laid down in the aforesaid Indian Accounting Standard and other accounting principles generally accepted in India and has not disclosed the information required to be disclosed in terms of Regulation 33 of the Listing Regulations, zor5 including the manner in which it is to be disclosed, or that it contains any material misstatement.
